Appi'lcation filed July '8, 1911. Serial No. 637,421.

To all whom it may concern:

Be it known that I, Auornn E. GRUM, a citizen of the United States, and a resident of Mobile, in the county of Mobile and State of Alabama, have invented a new and improved' Valve, of which. the following is a full, clear, and exact description.

, My invention relates generally to valves, and, more particularly, to'a structure comprising a casing which permits the use of parts whereby a double-acting or a single acting valve construction is provided.

One of the principal objects of the invention is to provide a valve which, when used as adogable-acting valve, comprises cooperating parts, whereby the lower and upper valves may be accurately adjusted on their seats when the valve is being assembled or in taking up the slack from wear.

A further object of the invention is to provide a valve having operating means exteriorly of the valve casing, whereby the threads used in operating the valve are in convenient position for cleaning, inspecting,

and oiling, while the valve is in use under pressure,-the said threads being out of contact with the steam, thereby providing for greater durability and lower temperature of such parts.

A further object of my invention is the provision of a valve casing with a plurality of valves adapted for conjoint use, one of the valves being adapted to be used alone,

1. whereby an improvement in this art is proview of the bearing member for the lower valve shown in Fig. 4.

The body member or casing 1 has similar openings 2 at diametrically opposite points, the double valve seat 3 having the tapered sides 4, 5 and being positioned substantially 'at a central point within the casing, said seat being supported by the upstanding parts 6, 7. The'casing is adapted for connection to suitable pipes by means of threaded openings 8, '9. Adjacent the openings 2' and on the exterior thereof arescrew threads 2- of similar I bers in position.

Asshown particularly in Figs. 1 and 2, the closure member for the upper opening 2 is in the form of a bonnet 12 having a circular flange 13- thereon provided with screw threads adapted to cooperate with the threads adjacent the upper opening 2. At a central point on the lower portion l5-of the bonnet, a circular opening is provided into which a gland 16 is adapted to'be positioned; this gland receives packing material 17 in any desired quantity, said packing material beingretained in position by means of a cap 18. The upper portion 19 of the bo'nnet is of cylindrical construction,

having a plurality of threads 20 on its outer surface and extending longitudinally thereof, the valve stem 21 being concentric with the threads 20 and extending through this Patented Feb. 17, 1914..

cylindrical portion 19 and also through the v packing 17 and gland 16 into the interior of the casing.

the stem 21, a shoulc-er is provided,

which is adapted to cooperate with the cen- Adjacct the upper end of tral portion of a handle 23 secured to the stem by means of a pin 24 the under side of the handle being provided with a downwardlyextending cylindrical portion 25 having a plurality of screw threads 26.

formed on its interior cooperating with the.

threads 20 formed on the exterior of the portion 19. A suitable valve 27 is secured to the stem 21 and within the casing 1, the

lower end of the stem beyond the valve being provided-with a plurality of threads 28. These threads engage in similar threads 29 formed on the interior of the extending portion 31 of the lower valve 30. This eXtend- 7 ing portion (shown particularlyi-n Fig. 4) is positioned within a suitable opening in a bearing 32 which is contained within the lower opening 2 in the casing 1 and maintained in such position by means of the closure member 11.

Referring particularly to Fig. 1, it will be noted that within the openings at the op: posite sides of the casingare the shoulders 10 which extend around and inside the openings; the flange 13 which carries the gland and the packing material is provided with. a

shoulder lO which is adapted to lie closely .a ainst and engage the shoulder 10 within the upper opening. The beforementioned lower opening 2 is provided with a shoulder adapted to lie closely against the shoulder -10 within this lower opening, whereby theybearing is accurately positioned and 'movement within the opening'is prevented after the parts are assembled The handle23 being secured on the stem 21, turning of the handle in one direction will turn the stem and will also advance it through the portion 19 of the bonnet 12 by reason of the screw-threaded engagement between the part 25 of the handle and the part19 of the bonnet, and will bring the valve 27 away from the seat 3; this same movement also lowers the other valve 30 because of the threaded engagement between the lower end 28 of the stem and the portion 31 of this valve. Of course, turning the handle in the opposite direction brings the two valves toward each other and seats them' on the tapered edges 4, 5 respectively, of the valve seat, 'thereby eflectively closing the valve.

It is to be particularly noted that by placing the threads on the exterior of the portion 19 of the bonnet and placing the cooperating threads on the handle 23, I set, forth a construction which exposes the screw threads, thereby making them available for cleaning and oiling, and provide a more secure and rigid construction since all the parts within the casing'are perfectly plain. By reason -of'the fact that the openings 2 in the casing are at diametrically opposite points, and

I that the construction of the casing adjacent each one of these openings is similar to. the construction of the other, the casing may be securely tightened 1n position and the valves inserted later, this arrangement permitting.

the stem to project from either side of the casing as may be most desirable.

As shown particularly in Fig. 3, the lower valve may be omitted and the upper valve 27 used by itself. In this case the lower closure member 11 is placed inposition over the. lower opening 2 and provides a tight joint. In this arrangement, however, the pin 2i adjacent the top of the stem is withdrawn from the transverse opening in the handle 23 and is inserted directly into the opening 40 at the top of the stem. The shoulder 22 on the stem bears against the under side of the handle and the pin bears against the uppervside of the handle, so that a turning of the handle with the consequent movement thereof, causes the stem and the valve 27 to approach or come away from the valve seat 3. In this method of operation, the stem 21 moves directly up and down, no turning movement thereof taking place.

In order to permit grinding of the lower valve 30, I have provided a slot or equivalent construction, 100, in the lower end thereof which is adapted to be engaged by a I'have insured the correct positioning ofthe valve, when once adjusted; the threads on the bonnet 19 being equal to and in the same direction as the threads 29 in the interior of this lower valve, the travel of both valves is equal and the lower one is held against turning and consequent disarrangement. The valve as shown in'Figs. 1 and 2, may be taken apart, to a certain extent, and'repairs made in the interior thereof in the following way even though pressure is maint ained on one side of the valve. By removing the bonnet 12 and turning the stem 21 to free the lower end thereof from engagement with the portion 31 of the lower valve, the stem and upper valve 27 may be entirely withdrawn, the lower valve 30, however, being securely maintained in position against the valve seat 3 by reason of the pressure back of the valve. lVith the parts in this position, the upper valve may be repaired or the valve and stem may be renewed, or various other changes may be made without the necessity of removing the pressure to the left of the valve.

It is to be noted that the bearing 32,.pro-

.vided with the shoulder 1O enters into the opening in the lower portion of the valve casing and that the lower valve 30 with its extending portion 31 is positioned within the opening in this bearing. The opening in the bearing (Fig. 5) is preferably noncircular and the extending portion 31 of the valve is similarly shaped so that with the bearing maintained rigidly in position, the

lower valve is givena movement which is non-rotatable whenever the stem is turned. It is of some consequence in double-acting valves that the valves seat themselves simultaneously, in the present construction, the upper valve 27 may be properly seated, after vwhich'the lower valve may be entered into the opening in the bearing 32 with the threads on the stem 21 engaging the threads 29, the lower valve being brought home or seated by turning the bearing and the valve with a suitable tool as described. lYith the lower valve thus seated, it may be maiir tained permanently in such position by placing the lower closure member 11 in position, this closure member turning freely and not interfering or engaging with any part of the lower valve. The engagement between the lower portion of the bearing and the closure member 11 holds the bearing secured in position so that consequent turning of the handle or turning of the valve stem will move the valves sinniltaneously instant. As previously mentioned, the lOWer valve may be conveniently ground by merely removing the-upper valve and the closure member 11 and'turning the bearing 32 and the. valve by means of a suitable tool.

I A' consideration .of the drawings and the specification will bring out the .tollowing facts. By reason of the similar construction adjacent the openings at op osite sides of the valve casing, the spind e 21 may be "brought into position within the valve in either. opening; this is an advantage in that the valves may be reversed in the event of a reversal of fluid passing through the pipes.

The particular construction of the bonnet and the operating means for the spindle provide for cool. parts, thereby making "operationlof the valve quicker and simpler; it 15 also worthy of note that, when the upper valve is fully opened, the engagement of the top portion of this valve withthe gland makes a SlQRIDtIgllbjOlHt or hearing enabling the valve to be repacked while in use and also relieving the packing of pressure when the valve is opened; finally the arrangement of the parts as a whole makes for a construction which is'new. and useful, the inventive idea involved. b g included claims.
